To all whom it 'may concern:`

lie it known that I, JULLUS LA-RSE'N, citizen of the Kingdom of Denmark, and a resident of Silkegade 13, Gopenhagen, Denmark, mamifacturer, have invei'ited new and useful Improvements in Shuttle Mechanism, of which the following is'a specification.

By sewing machines horizontal shuttles have now and then been in use, although the' tal shuttle, which is "so arranged, that it seizes the thread and holds it. fast, so that the y needle can without stopping go straight v down and then again at once straight up,

the vupper edge of the ring formed Shuttlebed being provided with a horn, .that holds onto the thread during the formation of the Stitchi l The invention is Shown in the accompanying drawing, in whichy i Figures 1, 2 and show the shuttle and the upper part of the shuttle box partly 'in sec' tion in thre different positions during the formation o y the stitch; and Fig. 4 shows the shuttle in the position shown in Fig. l, but

looked at from above.

The shuttle 2 is of the shape shown in Fig. l, and is provided with a horn 5, t-he lShuttle being rotatably mounted ina lixed `ahuttle bed-1, which is provided atl a point in its periphery 'with a slanting incision 4, forl'ning a hook, the incision slanting downwardly in the opposite direction to the horn ii. 4 ly'hen the needle 8 has reached the lowestpointin this movement, the upper thread 7 caught by the horn 5 of the shuttle, which shuttle; rotates clockwise. a

The movement of the Shuttle will engz'rgethe tlxreadwith the hook and a continued rotation of the shuttle will carry the bobbln which is placed in the depression of the shuttle through the loop of thread as shown l' in Figs. 2 and 3.

, Having now described my invention, what I claim and`l desire to secure by Letters `1)atent, is-

A4In a sewing machine, a fix-ed circular r shuttle bed, and a shuttle mounted thereon,

the shuttle being provided with a horn for' engaging the upper thread, and the shuttle bed with an incision forming a. hook for engaging and retaining the thread during the movement. of the shuttle in one direction, whereby the shuttle is thrown through the loop of the thread, the direct-ion of the hook being' opposite to the direction of the horn.

Signedby me at Copenhagen, Denmark, this 13th' day of Xovember 1906.
